I played a round of sudden death blitz to see how the game runs on my machine (it runs great) and to hopefully earn enough $$$ for a custom class before jumping in to crossfire. Blitz seems a lot easier than on the xbox and around level 165 I finally gave up and let the bots have at my ball. Finally took it down at round 169 (second place overall out of like five people who have played the mode!) For some reason, the $20,000 I earned during that round of blitz didn't get added to my cash. I don't know if this is an intended change, a bug you guys know about, or what, but I didn't see a thread about it.
I'm also not getting any Healing stats kept from blitz. At the end of the match I'm told I get the Healing Protags but it still says 0 healing in the career menu. Bot kills, Hacks and completion highlights do keep. Also I'm pretty sure my money is keeping now.
